DOOR-KEY.

' SPECIFICATION forming part of Letters Patent No. 598,560, datedFebruary 8, 1 898.

Application filed May 7,1897. Serial No. 635,615- (No model.)

To all whom it may concern;

Be it known that I, WILLIAM H. DAGGETT, a citizen of the United States,residing at Somerville, in the county of MiddleseX and State ofMassachusetts, have invented a new and useful Improvement in Door-Keys,of which the following is a specification.

My invention consists of an attachment to the ring of a door-key for thepurpose of enabling one to distinguish it by the sense of touch fromother keys with which it is kept or carried.

The advantages of the construction herein described and claimed overthat shown in Letters Patent issued to me August 6, 1895, and numbered543,852, consists of its adapt ability to a greater variety of keys, ofholding more firmly to the key, and of a reduction in the cost ofmanufacture.

In the drawings, Figure 1 is a perspective view of the hook A. Fig. 2 isa plan view of the bridge-piece C before it is bent into its finalshape. Fig. 3 is a perspective view of the attachment secured to thekey.

A is apiece of sheet metal, preferably brass. It is Wider at each endthan at the middle and is bent into the form of a hook a at one end andhas a screw-thread cut in its edges at the other end I) for the purposeof receiving the screw-cap d.

Referring to Fig. 2, the opening 0 is made T-shaped, so as to admit theend I) of the piece A and then to receive its narrow portion into thestem of the opening, where it fits snugly and can have no lateral play.When the piece A has been inserted in its place, the tongue e, formed bya portion of the metal cut out to make the opening 0, is bent back intothe opening and secures the piece A against any forward-and-backwardplay. Notches g g are cut in the ends of the bridgepiece 0 to fit overthe edges of the key-ring when it is secured to the key. When the partsare bent into the forms shown in Fig. 3, the hook a is inserted in thering of the key, the notches g g of the bridge-piece are 1. adjusted tothe top of the ring, and the screwcap d is then turned down hard ontothe bridge-piece 0 to firmly bind all parts together and to thekey-ring.

The form of key shown in Fig. 3 is in common use, and, having only roundholes in the head, the device shown in my said former patent cannot beconveniently applied to it. The construction herein described andclaimed is .especially fitted for it and is adaptable to all forms ofkeys in use. I also find that in the use of the arrangement herein shownthe screwcap is much more secure and that any tendency of it to unscrewand work off is entirely overcome.

IVhile I prefer to make all the parts of my screw-thread at the other, abridge-piece made of a flat metal strip having its ends bent at rightangles and having an opening to admit.

the strip A, the hook being inserted in the ring of the key, the ends ofthe bridge-piece bearing on the outside of said ring and all clampedtogether by means of the screw-cap (Z, substantially as described.

2. The combination of a key, a flat metal strip A, having a hook at, atone end, and a screw-thread on its edges at the other end I), said stripbeing narrower at the middle than at its ends, a flat metal bridge-pieceO, having a T-shaped opening cut out of the same, and its ends turneddownward at right angles, the hook being inserted in the ring of thekey, the strip A, being held in the stem of the opening 0, by the tonguee, the bridgepiece 0, bearing on the outside of said ring and all boundtogether by the screw-Capri,

substantially as described.

In witness whereof I hereunto set my hand this 5th day of February, A.D. 1897.
